Update 20 July 2023
17:30 | On the 11th, 14th, and 19th of July 2023, Adobe has released security bulletins regarding a total of seven vulnerabilities in the product Adobe Coldfusion. Three of the seven vulnerabilities are critical. The vulnerabilities are applicable to the following versions: ColdFusion 2018, ColdFusion 2021, and ColdFusion 2023.
The three security bulletins describe vulnerabilities that could lead to arbitrary code execution. Two out of the three security bulletins describe vulnerabilities that could lead to a security feature bypass.
WARNING: The earlier advice from Adobe regarding the workaround by enabling lockdown-mode can be bypassed by chaining multiple vulnerabilities. These are the so-called “security feature bypass” vulnerabilities.
There are software updates available to remediate the vulnerabilities. Our advice is to apply them as soon as possible.
Achtergrond
On the 11th, 14th, and 19th of July 2023, Adobe has released security bulletins regarding a total of seven vulnerabilities in the product Adobe Coldfusion.

The three security bulletins describe vulnerabilities that could lead to arbitrary code execution. Two out of the three security bulletins describe vulnerabilities that could lead to a security feature bypass.
Risico
The vulnerabilities CVE-2023-29298, CVE-2023-38203, and CVE-2023-38205 have a CVSSv3-score of 9.8. The CVSS-scale runs from 0 to 10. A score of 9.8 or higher is rare and implies a high risk of exploitation with high impact. All three vulnerabilities are unauthenticated remote code execution vulnerabilities, allowing an unauthenticated remote attacker to execute code.
The vulnerabilities are exploited in the wild and there is also a proof-of-concept exploit publicly available.
Advies
The vulnerabilities CVE-2023-29300, CVE-2023-38203, and CVE-2023-38204 are related to extracting untrustworthy data without performing sufficient verification of the data. Below an overview of all vulnerabilities:
